How many number 10 wire can fit into three quarter inch emt conduit?

The number of 10 AWG wires that can fit into a three-quarter inch EMT conduit depends on the conduit fill calculations based on the National Electrical Code (NEC). For three-quarter inch EMT, the maximum allowable fill for 10 AWG wire is typically around 10 wires, considering the 40% fill rule for conduits with multiple conductors. However, this can vary based on insulation type and other factors, so it's essential to consult the NEC tables for precise calculations. Always ensure to follow local codes and regulations.
